[0009] Preferably, the oblique impact mechanism includes a second hydraulic cylinder, a cylinder sleeve is mounted on the outside of the second hydraulic cylinder, rotating rods are fixedly installed on both sides of the cylinder sleeve, and a clamping shell is fixedly installed on both sides of the inner wall of the arc plate, the clamping shell and the rotating rod are rotatably engaged, a support rod is fixedly provided at the telescopic end of the second hydraulic cylinder, a two-way telescopic cylinder is rotatably provided inside the support rod, a clamping seat is fixedly provided at both ends of the two-way telescopic cylinder, an arc groove is opened on the inner side of the clamping seat, and blocks are rotatably installed on both sides of the arc groove.

[0010] Preferably, a connecting seat is fixedly provided at one end of the second hydraulic cylinder away from the support rod, a second connecting rod is rotatably installed inside the connecting seat, both outer ends of the second connecting rod are rotatably connected to the first connecting rod via rotatably connected pull rods, a swing hydraulic cylinder is rotatably provided in the middle of the outer part of the first connecting rod, and the end of the swing hydraulic cylinder away from the first connecting rod is rotatably installed inside the T-shaped frame.

DETAILED DESCRIPTION

[0017] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figure 1-Figure 6A novel CNC deep hole boring machine shown in the figure comprises a first track platform 1, a second track platform 3, a boring machine head 9, and a planetary frame 26. The first track platform 1 is provided with two groups, and the two groups of first track platforms 1 are respectively provided on both sides with the second track platform 3 as the center. The first track platform 1 is connected with a slide 16 through a first screw drive mechanism 2 provided inside, and the slide 16 is slidably connected with the first track platform 1. The boring machine head 9 is provided on the upper surface of the slide 16. The second track platform 3 is connected with a moving seat 22 through a second screw drive mechanism 19 provided inside, and a box body 23 is provided on the upper surface of the moving seat 22. A slide 5 is fixedly provided above the box body 23, and the slide 5 is slidably connected with the second track platform 3. The box body 23 is connected with a moving table 4 through a lifting mechanism provided inside, and a frame fixing mechanism is provided on the upper surface of the moving table 4. Guide rails are arranged above the first track platform 1 and the second track platform 3; The first screw drive mechanism 2 and the second screw drive mechanism 19 are both composed of a motor, a screw, a bearing, a slider and other structures.

[0020] The lifting mechanism includes a third hydraulic cylinder 21 fixedly arranged on the inner side of the box body 23, and a stop platform 24 is fixedly arranged at the telescopic end of the third hydraulic cylinder 21. A slot 20 is opened in the middle of the slide 5. The upper surface of the stop platform 24 is connected to the lower surface of the moving platform 4. The moving seat 22 slides and fits with the inside of the second track platform 3. The area of ​​the slot 20 is the same as that of the box body 23. By arranging the third hydraulic cylinder 21 at the box body 23, the purpose is to be able to lift the stop platform 24 and the moving platform 4, so as to facilitate pushing the workpiece to the processing position of the boring machine head 9 on both sides for processing.

[0021] The fixing mechanism includes a support base 8 fixedly arranged on the upper surface of the movable platform 4, a rectangular groove is opened in the middle of the support base 8, and a plurality of rollers 30 are rotatably installed inside the rectangular groove. Both ends of the support base 8 are connected to a T-shaped frame 25 through a propulsion mechanism, and the arrangement of the plurality of rollers 30 cooperates with the subsequent rotation of the planetary frame 26.

[0022] The propulsion mechanism includes a first hydraulic cylinder 7 arranged at one end inside the support seat 8, the telescopic end of the first hydraulic cylinder 7 is fixedly connected to the outside of the T-shaped frame 25, an arc plate 17 is fixedly arranged above the T-shaped frame 25, a mounting frame 10 is fixedly arranged outside the arc plate 17, a pressing mechanism is arranged at the lower part of the inside of the mounting frame 10, an oblique pressing mechanism is arranged on the inner side of the arc plate 17, the planetary frame 26 is arranged between the two groups of mounting frames 10, and the outer surface is rollingly fitted with multiple rollers 30. The first hydraulic cylinder 7 can drive the T-shaped frame 25, the arc plate 17, and the mounting frame 10 to move above the second track platform 3. On the one hand, it is convenient for the pressing mechanism to clamp the planetary frame 26 during operation, and on the other hand, when not processing, a larger space is freed up for the assembly of the planetary frame 26.

[0023] The pressing mechanism includes clamping arms rotatably installed at both ends of the inner side of the mounting frame 10, and the limiting wheels 29 are rotatably installed inside the two sets of clamping arms, and the limiting wheels 29 are movably opposed to the outer side of the planetary carrier 26. The purpose of setting the limiting wheels 29 is to clamp the lower end of the planetary carrier 26. When the planetary carrier 26 rotates, the limiting wheel 29 on the other side is away from the planetary carrier 26, and the currently opposed limiting wheels 29 cooperate with the rotation of the planetary carrier 26 by virtue of their own rotatable function.

[0024] The oblique impact mechanism includes a second hydraulic cylinder 18, a cylinder sleeve 11 is sleeved on the outside of the second hydraulic cylinder 18, a rotating rod 33 is fixedly installed on both sides of the cylinder sleeve 11, a card shell 34 is fixedly installed on both sides of the inner wall of the arc plate 17, and the card shell 34 and the rotating rod 33 are rotatably matched. A support rod 28 is fixedly installed on the telescopic end of the second hydraulic cylinder 18, and a two-way telescopic cylinder 35 is rotatably arranged inside the support rod 28. A card seat 13 is fixedly arranged on both ends of the two-way telescopic cylinder 35, and an arc groove 31 is opened on the inner side of the card seat 13. Both sides of the arc groove 31 are rotatably installed with a sticker 32. When the second hydraulic cylinder 18 rotates, the corresponding cylinder sleeve 11 will drive the rotating rod 33 to rotate inside the card shell 34, so that the second hydraulic cylinder 18 can be more stable when obliquely impacting, and the planetary frame 26 can be prevented from rotating when processing both sides of the planetary frame 26; The two-way telescopic cylinder 35 can adjust the clamping seats 13 at both ends according to the internal structure spacing of the planetary frame 26, so that the clamping seats 13 can be accurately clamped on the outer surface of the planetary frame 26 when clamping; The block 32 is rotationally connected to the arc groove 31. When the second hydraulic cylinder 18 drives the planetary carrier 26 to rotate, the block 32 rotates with the outer surface of the planetary carrier 26 by virtue of greater resistance and contact, thereby cooperating with the rotation of the planetary carrier 26.

[0025] The second hydraulic cylinder 18 is fixedly provided with a connecting seat 15 at one end away from the supporting rod 28, and the second connecting rod 12 is rotatably installed inside the connecting seat 15. Both ends of the outer side of the second connecting rod 12 are rotatably connected to the first connecting rod 6 through the pull rod 14 connected by rotation. A swing hydraulic cylinder 27 is rotatably provided in the middle of the first connecting rod 6. The end of the swing hydraulic cylinder 27 away from the first connecting rod 6 is rotatably installed inside the T-shaped frame 25. Through the extension and contraction of the swing hydraulic cylinder 27, the first connecting rod 6 pushes and pulls the pull rod 14, and the second connecting rod 12 adjusts the angle of the second hydraulic cylinder 18 above. At this time, the pull rod 14 is pulled. As the pulling force increases, the bottom of the planetary carrier 26 can rotate along the side elevation when in contact with the roller 30. Repeated shaking and pulling can quickly drive the planetary carrier 26 to rotate according to the drilling needs of the outside of the planetary carrier 26. During this period, the swing hydraulic cylinder 27 and the second hydraulic cylinder 18 at one end can be driven, and the second hydraulic cylinder 18 at the other end can be clamped on the outside without contacting them. On the one hand, it ensures that the planetary carrier 26 can rotate without any obstruction. On the other hand, when the planetary carrier 26 rotates, the planetary carrier 26 can be clamped on the outside to avoid misalignment during rotation.

[0026] Working principle: When in use, the planetary frame is placed on the upper surface of multiple rollers 30 through an external lifting mechanism, and the first hydraulic cylinder 7 drives the T-shaped frame 25 to approach each other, causing the limiting wheel 29 at the lower part of the interior of the mounting frame 10 to abut against the lower part of the exterior of the planetary frame 26. The second hydraulic cylinder 18 inside the mounting frame 10 drives the support rod 28 at the telescopic end to move according to the position of the planetary frame 26. During this period, the two-way telescopic cylinder 35 adjusts the card seat 13 at both ends according to the spacing of the internal structure of the planetary frame 26, so that the arc groove 31 inside the card seat 13 corresponds to the external tangent surface of the planetary frame 26, and then with the movement of the support rod 28, the card seat 13 is clamped against the outer facade of the planetary frame 26. The sticker 32 inside the card seat 13 is pressed by the two-way telescopic cylinder 35 to stably clamp the planetary frame 26. At this time, the boring machine head 9 above the first track platform 1 is driven by the first screw drive mechanism 2 to approach the planetary frame 26, and the boring machine head 9 at the corresponding position drills holes on the outer side of the planetary frame 26. When the drilling of the current position of the planetary frame 26 is completed, the first connecting rod 6 pushes and pulls the pull rod 14 through the extension and contraction of the swing hydraulic cylinder 27 at one end, and the second connecting rod 12 adjusts the angle of the second hydraulic cylinder 18 above. At this time, the pulling force increases, and the bottom of the planetary frame 26 rotates along the side elevation under the contact with the roller 30, and the block 32 inside the holder 13 rotates with the planetary frame 26. Before the rotation process, the other end is driven by the second hydraulic cylinder 18 and the two-way telescopic cylinder 35 to make the holder 13 at the corresponding position move to the side of the installation frame 10, so that the current holder 13 is separated from the planetary frame 26 and placed. The swing hydraulic cylinder 27 waiting to rotate on one side of the planetary carrier 26 drives the operation, giving the planetary carrier 26 space to rotate, avoiding the occurrence of rotation obstruction due to the fact that both of them are against the planetary carrier 26. When drilling continues at other positions after rotation, the support rods 28 at both ends return to the original oblique upper position, prompting the second hydraulic cylinder 18 to push the support rod 28 and the holder 13 to be stuck on the outside of the planetary carrier 26 at one side obliquely above. In this way, the step of repeatedly manually fixing the planetary carrier 26 can be omitted. In the drilling operation, it can be quickly used in conjunction with the boring machine to improve the processing efficiency of the boring machine.
